lesmor: I am still undecided which amp to go for
What are the views of members between the 2 amps in the subject text?Best thing to do is get a listen if you can. Both are excellent amplifiers, and yes, the Yamaha is pretty hard to beat. The Pioneer does have a thinner sound than the Yamaha, but the mention in this thread of it sounding bright or harsh is probably a little overstated. We used to have ours in our main AV room, which is quite a reflective room at the moment, so tends to show up brighter equipment. The Pioneer has a great feature caled 'X-Curve', which allows you to tail off the HF response in 1dB steps, making the overall sound smother - which we found a very useful feature.
The Pioneer is more suitable to speaker packages that have similarly sized speakers, as it only has a single crossover point - not a good thing if you have big floorstanders with small rear speakers or centre. Obviously this is a beter choice for those with THX requirements.
